You don't offer any source code, but people are often "gotcha"'d by the
fact that FreeBSD really means "must be zero" when it describes spare
entries in a sockstat as MBZ. Linux doesn't care.

If you have a

	struct sockaddr_in a;

try changing it to

	struct sockaddr_in a = {};

- C semantics for structure initialisation mean that unspecified fields
are set to zero.

Cheers,
